Constructed from aluminum oxide abrasive with a vitrified bond, it measures 7 inches in diameter and 3\/4 inches thick with a 1-1\/4 inch arbor hole and a one-side recess of 1\/4 inches deep by 3 inches in diameter. The 46 grit, H hardness coarse grade is optimized for aggressive material removal while maintaining wheel integrity at speeds up to 3600 RPM. Licensed HVAC, plumbing, and industrial maintenance technicians will find this wheel suited to high-production grinding operations on a range of common metals.\u003c\/p\u003e\u003cp\u003eThis wheel is rated for use on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is compatible with cylindrical grinders and surface grinders in both shop and field maintenance environments. The coarse 46 grit designation makes it appropriate for rapid material removal rather than fine finishing passes. The non-porous vitrified bond provides consistent abrasive exposure throughout the wheel life, making it a reliable choice for production grinding tasks in fabrication and maintenance shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 5 recessed wheel geometry with one-side recess: 1\/4 inches deep, 3 inches recess diameter\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent cut and long wheel life\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade for aggressive stock removal on ferrous and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eH hardness code rated for surface grinder and cylindrical grinder use\u003c\/li\u003e\n\u003cli\u003eMaximum operating speed of 3600 RPM\u003c\/li\u003e\n\u003cli\u003eSpecification code 46H8V32A for precise cross-referencing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders.
